This message is directed at users of NetBSD/alpha and NetBSD/sparc64. If
you don't use those ports, then you can ignore this.
Various bits of the kernel were recently changed to test for _LP64 being
defined by the compiler/C preprocessor. This requires a compiler update,
otherwise your kernel will fail to function properly, or fail to compile
altogether.
What this means is that you should make ABSOLUTELY SURE that you build
a new compiler before the next time you build a kernel after updating
your sources.
You can do this using the "-t" option to build.sh, or by simply letting
build.sh build the entire system for you from scratch, "release-style".
